\VINSLOW ALLDERDICE, OF WARREN, OHIO, ASSIGNOR TO WILLIAM H. ALLDERDIOE, OF XVASHIN GTON, DISTRICT OF COLUMBIA.

WATER PURIFIER AND COOLER.

SPECIFICATION forming part of Letters Patent No. 497,743, dated May 16, 1893.

Application filed December 8, 1892- To all whom it may concern:

Be it known that I, WINSLOW ALLDERDIOE, a citizen of the United States, residing at \Varren, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Water Purifiers and Coolers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in water purifiers and coolers, and it consists of certain novel features hereinafter described and claimed.

Reference is had to the accompanying drawings, in which the same parts are indicated by the same letters throughout the several Views.

Figure 1 represents a plan view of the water purifier and cooler with the covering plate removed. Fig. 2 represents a central vertical section of the device shown in Fig. l.

A represents the inlet pipe connected to a hydrant or other water supply where a sufficient head of Water is provided. A represents an enlargement of the said pipe forming a valve seat for the valve or cock B. Beyond this valve seat are two passages for the water A and A separated from each other by the partition to and opening into the passages A and A in a casting on either side of the filter O. Hollow screws D form a means of holding the filter in place, and at the same time provide channels for the passage of the water from the said passages A and A through the said filter; for this purpose, each of the said hollow screws is provided with two holes cl opening into the interior of the hollow screw from the channels A and A respectively. Beyond the filter, the two channels for the water converge as at A and A, but being still separated by the partition (1', these channels open into the interior of the valve seat A provided with the three-way cock B having ports 12 b and b adapted to allow the water from the filter t-o flow either into the delivery pipe A or into the waste pipe E and drain F, shown in dotted lines in Fig. 2.

H represents a vessel suitably insulated,

Serial No. 454,478. (No model.)

and mounted on a pedestal H This vessel is provided with two chambers H H the latter containing the closed metallic ice box H and the former being surmounted with the heating dome H The vessel H is preferably composed of an inclosing shell h a space h filled with insulating material, or simply air, and an inner shell 7L2. This vessel is surmounted by a dome-shaped cap its having air holes h. h represents the cover of the vessel beneath the said cap, and It represents a water-tight partition separating the chambers H and H 71 represents the roof of the box H which holds the ice I, and rests on feet 71 clear of the bottom of the chamber H it represents the door opening from the exterior into the ice box H and h represents a drain cock from the base of the said ice chamber for drawing off the melted ice.

The pipe 7c leads upward from the chamber l-I into the heating coil K over the Bunsen burner L connected by the pipe L to a suitable gas pipe. The heating coil K leads downward into the condensing and cooling coil K which opens at its lower end by means of the pipe 76' into the chamber H represents a drain cock for the said chamber H The chamber [1 is provided with an overflow pipe M having a check valve m adapted to open outward but to remain normally closed.

The operation of the deviceis as follows: The water coming from the hydrant by means of the pipe A passes through the valve B, the passage A, the upper hollow screw D, down through the filter O, the lower hollow screw, the passage A, the ports 19 and b in the valve B, and the inlet pipe A into the chamber H. Rising in this chamber until it reaches the top thereof, it passes into the pipe 76 and the heating coil K, where the burning gas converts a portion of the Water into steam and brings the whole of it to a sufficiently high temperature to kill all the germs that may be therein contained. From the heating coil K, the hot water and steam pass down through the condensing and cooling coil K, finally dripping into the chamber H through the pipe 7a. This chamber 11 is the cooling chamber, the water therein being cooled by contact with the exterior of the metallic walls of the chamber H containing the ice I. The water, after having been cooled may be drawn off by means of the faucet 10 It will be seen that in the chamber 11' the inflowing water enters at the bottom and cools the lower portion of the condensing and cooling coil K, while the water rising in the pipe from the upper portion of said chamber has been already heated to a considerable extent by the hotwater and steam descending through the coil K. In this way the Water is gradually heated and is gradually cooled and advantage is taken of the natural convection currents which-will occur. It will be seen that in the cooling chamber H the water is not in contact with the ice, and is .drawn from a contract-ed space in the lower portion of the chamber after having been in contact with the conducting walls of theice chamber H It will be seen that thecold water would naturally descend to the lower portion of the vessel H at which position the faucet k is placed:

in order that the water from thej'melting part'of the ice chamber H is provided;

The-icechamb'er'H is supported on legsh so that thewater in the chamber H may fiow' beneatlrit, thus 'increasin g the cooling surface. Since thefilter G will speedily become soiled with vthesedimentaiy matter found in ordinary hydrant water, it will become necessaryto either change the filter frequently or to.

wash'itiout. I prefer-to wash itrout": inthe manner hereinafter described.

have become soiled, the cock B shouldbe turned so thatthe ports band b'-'shou ld.be

turned so that the'port b may open into. the.

passage A and the port b into thew'aste. pipe E, the waterwill then flow from the pipe A shows sufficient clearness the cooks maybe turned .back into'the position shown in Fig. 2, and the process of purifying the water may be resumed.

I'do'notclaim any particular form *offilter, there being manywell known in the art which couldbe satisfactorily used with the herein 1 described device.

The supply of water admitted to the vessel H is controlled either by the valve B, or by the valve B; :and any excess of water admitted to the vessel 11 overflows through the. valve m and pipe M. This valve readily opens outward for the overflow of the water or the egress of compressed air due. to the filling of the chamber H but it resists all pressure from the outside and hermetically closes the chamber H to atmospheric impurities.

Having thus described my invention, what I claim, and desire to secureby Letters Patent 0f the United States, is-
